SeaRey Landing. Development of the aircraft that became the SeaRey began in the 1970s with the introduction of the Advanced Aviation Hi-Nuski ultralight. In the early 1980s Stanley Richter, his son Wayne Richter, Wayne's wife Nina Richter and Wayne's son Kerry Richter established Advanced Aviation where they designed and manufactured a number of different designs.
Sea Ray designs and markets more than 40 models ranging in boats from 18 to 65 feet (5.5 to 19.8 m). Sea Ray was the first boat manufacturer to use fiberglass in its pleasure boat construction, and it also pioneered the molded-in swim platform when it launched Ski Ray dedicated water skiing tow boats in 1991. [9] In 1995, it acquired a new ...
hobbyist-built DPV with T500 thrusters . A DPV usually consists of a pressure-resistant watertight casing containing an underwater thruster, or a battery-powered electric motor, which drives a propeller The design must ensure that the propeller cannot harm the diver, diving equipment or marine life, the vehicle cannot be accidentally started or run away from the diver, and it remains ...

A magnetohydrodynamic drive or MHD accelerator is a method for propelling vehicles using only electric and magnetic fields with no moving parts, accelerating an electrically conductive propellant (liquid or gas) with magnetohydrodynamics. The fluid is directed to the rear and as a reaction, the vehicle accelerates forward. [1] [2]

An alternative to the supercavitating propeller is the surface piercing, or ventilated propeller. These propellers are designed to intentionally leave the water and entrain atmospheric air to fill the void, which means that the resulting gas layer on the forward face of the propeller blade consists of air instead of water vapour. Less energy is ...
The Super Dvora Mark III-class patrol boat is the latest generation of the Dvora family of fast patrol boats or fast attack craft (FPB/FAC). Manufactured by IAI Ramta in 2004 [1] these vessels are capable of travelling up to 50 knots (93 km/h; 58 mph) in littoral waters thanks to its state of the art thrust vectoring control Articulated Surface Drives (ASD) while holding various armaments ...
